I'm willing to sell (or buy) EVE Online game time cards ( http://www.eve-wiki.net/index.php?title=Game_Time_Card ) that can be traded in-game, between characters. These GTCs are bought in 60-day amounts, but come in 2 in-game items that can each separately be redeemed for 1 month of game play time.

At this point I'd probably be looking at 20BTC per 30 day GTC, or 40 for 60 days.

If anyone is interested in this, please feel free to PM me and we can exchange contact information.
